s'rovn AND RANGE.

, Be it known that I, LOYD Seances, a citizen' of the United States, residing at St.. Louis, Missouri, have invented a certain new and useful Improvement in Stoves and Ranges, of which the following isa full,

This invention relates to cooking stoves, and particularly to ranges of the type which casing inside of which an asbestos lining is absorbed by the portionsof the steel casing which form the outer walls of the smoke flue. The ranges of this type which are now in general use have not proven entirely satisfa'c ry becauserust forms on the inner surface of the steel casing and in ?the course of three or four years eats completely through the casing, the rust being caused by the moisture which the asbestos lining absorbs anddeposits on the inner surface of the steel casing. v

The main object of my invention 18 to rust out, the range beingiso constructed that moisture in the insulating material used to'line the smoke flue will have absolutely casing of the range. And another object is soot cannot escape froin'the smoke flue and pass into the warmlng oven which hes under- I Other objects and desirable features of will be hereinafter pointed t v t ,Figure I of the drawingsis a vertical seetional view of a range constructed in accordance with my invention;- and Fig. 2 is a offthe 'ran and".thei-heatainsulating materialthat hnesthes'rnolre flue,

tom of the oven to the uptake flue E. A-

heat-insulating lining F of sheet asbestos or some other suitable materlah-is arranged in the smoke ,flue ad acent the portions of the casing A which form the outer walls of said flue so as to hold the heat in the oven and prevent it from being absorbed by said outer casing. A rust-proof lining G formed of sheet copper or some other suitable material, is arranged between the heat-insulating lining F and the outer casing A so as to prevent any moisture in the smoke fluefrom collecting on the inner surface of the casing A. The heat-insulating lining F can be retained in position in various ways, as for example, by means of a grille or grating 1 which is secured to the outer casing by bolts 2 or other suitable fastening devices, said bolts passing through openings in the heatinsulating. l ning F, the rust-proof lining G, and the casing A and thus securely clamping all of said elements together.

The inst-proof lining G can be formedin various ways but I prefer to' form the major portion of said rust-proof lining from a single sheet of material pressed ,into the shape shown in Fig. 2, so as to form a wall 3- which covers the bottom Wall 4 of the smoke flue, a wall 5 which covers that portion of the casing A which forms the vertical side wall of the flue, an upwardly projectingdiange 6 on the wall 3 which covers the portions of the casin A that form the side walls of the lower orizontal portion of the flue, and inwardly projecting flanges 7 on the wall 5 which cover the portions of the casing A that form the front and rear walls of the vertical portion of the flue. Separate pieces of material 8 are preferably used for covering the portions of the casing which form the rear and front walls of the upper horizontal portion of the flue but, if desired, the entire .rustroof'llnin G could bafomied from a sing e'sheet."o material rom sheet steel,

. To overcome t e possi ility of soot esca ing from the snioke flue and passin into t e H which s located elow the warming joven smoke flue, as shown in Fig. 1, I prefer to form the rust-proof lining G in such a manner that no open joints or cracks occur at the junction of the horizontal and vertical walls of said lining and the flanges on said walls. This can be accomplished in various ways, as for example, by forming folds or plaits 6 where they meet the flanges 7 and inserting one or more fastening devices 10 through the overlapping portions of said flanges so as to securely connect them together. I do not wish it to be understood, however, that mybroad idea is limited to this exact construction or, in fact, to a rust-proof lining of any particular shape or design for my invention broadly stated consists in a stoveor range having a lining of rust-proof material arranged between the outer casing and the heat-insulating material arranged inside of said casing irrespective of whethersaid heat-insulating material is used only in the flue or on other portions of the casing.

The flange 6 on the rear edge of the horizontal wall 3 of the rust-proof lining is provided with an opening 11 through which the spectively,

products of combustion pass into the uptake flue E, as lndicated by the'arrows in Fig. 1,

and the flange at the front edge ofsaid horizontal wall 3 1s provided with a clean-out wall 3 being provided with downwardly projecting lips 11 and 12*, reat the lower edges of said openings so as toovercome the possibility of soot dropping downwardly into the warming oven H.

The outercasingvof a range of the construction above described will last indefinitely'for the rust-proof lining G prevents the formation of rust on the inner surface of said casing, and as the portion of said lining which lies above the bottom wall 4 of the lower horizontal portion'of the flue is subthe plate stantially box-shaped it will be impossible for soot to pass into the warming oven through the joints between the casing A and 4 which forms. the top of said Warming oven horizontal portion of the flue. very desirable feature of such a construction is that air cannot lea-k through. the joints between the plate 4 and the casing and thus cool oit the bottom of the oven and retard the free circulation of the products of combustion, the rust-proof lining being so constructed that the smoke flue is practically air-tight.

I, of course, wish it to be understood that my invention is not limited to a stove of the exact construction herein shown, and while I have herein illustrated my invention embodied in that type of cookin stove commonly termed a range, it wi 1,0f course, be understood that any stove could be constructed in this manner, and therefore the Still another in the flanges 6 adjacent the points and the bottom wall of the used in the claims should be term range type of cooking construed as covering any stove.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A stove having an outer casing formed of material that is liable to rust, a heat-insulating lining arranged inside of said casing,

and a metallic rust-proof lining interposed between said heat-insulating lining and easing.

2. A stove having an outer casing formed of metal that is liable to rust,'a lining of heat-insulating material in the smoke flue ofthe range, and a lining of rust-proof metal interposed between said casing. and heatinsulating lining.

3. A stove having a sheet steel outer casing which is liable to rust, a heat-insulating lining arranged inside of said casing, and a lining of rust-proof metal arranged-between said heat-insulating lining and portions of 'the inner surface of said casing.

4. A' stove having a sheet steel outer casing which is liable to rust, a lining of heat-- insulating material arranged in the smoke flue, and a rust-proof metallic lining arranged between the casing and said heatinsulating lining.

5. A range having a sheet steel outer casing, an asbestos lining in the smoke flue, and a copper lining interposed between said asbestos lining and casing.

6. A range having a baking oven and a warming oven arranged under said baking oven, a smoke flue lying between said ovens, the bottom. wall of said smoke flue and the top wall .of said warming oven being formed by a plate of metal which is connected to the outer casing of the stove, and an independent layer of rust-proof metal arranged above said plate and having upwardly projecting. flanges that prevent the soot which accumulates on said layer from escaping from same and enteringthe warming oven.

7. A stove having an outer casing formed of metal that is liable to rust, a smoke flue whose walls are formed partly by said outer casing, a lining of heat-insulating material arranged in said flue, and a rust-proof lining arranged between said casing'and heatinsulating material for preventing rust from forming on the inner surface of said casing, the major portion of said rust-proof lining beingformed by a single plate of rust-proof.- metal that is bent or pressed so as to conform to the shape of said flue. 8. A range having an outer casing formed of material that is liable to rust, a bakin oven, a smoke flue that extends across sai oven down one side of same andthence imder the bottom of the oven, and a rust-proof lining arranged inside of said casing and. formed principally by a single sheet of metal bent to produce a horizontal wall that lines the bottom of the smoke flue, a vertical wall that lines the side of the smoke flue, and flanges on said walls that line the front and rear walls of said flue.

9. A range having a sheet steel outer casing, a baking oven arrangedinsidc of same and spaced away therefrom so as to form a smoke flue which extends across the top of the oven down one side of same and thence under the oven to an up-take flue, a member arranged under the bottom of the oven which forms one wall of the portion of the smoke flue which extends under the oven, 21
